The CSS 11000 uses the ArrowPoint Content Aware (ACA) service to gather
response time data for every flow for building statistical averages/variances
for every service and content rule. The best servers are used, while the slow
servers are pruned from the eligible list. This service also can manage
persistent connections for e-commerce based on IP addresses (range), Secure
Socket Layer (SSL) application IDs, and cookies.
